The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate parameter of 7.9% per day. Find the half-life of this substance (that is, the time it takes for one-half the original amount in a given sample of this substance to decay). Note: This is a continuous exponential decay model. Do not round any intermediate computations, and round your answer to the nearest hundredth. days
